Description

Technical Field

[0001] This utility model relates to the field of power head tool holder technology, specifically a multi-station power head tool holder. Background Technology

[0002] Slant bed CNC lathes are equipped with multi-station tool turrets or power tool turrets, offering a wide range of machining capabilities. They can process complex workpieces such as straight cylinders, inclined cylinders, arcs, and various threads, grooves, and worm gears. Multi-station power head tool turrets can install multiple power heads simultaneously, each capable of working independently or collaboratively to achieve parallel processing of multiple machining tasks. However, existing multi-station power head tool turrets often use a single-rod lead screw and nut combination structure to adjust the displacement of the power head assembly. During displacement adjustment, the single-rod lead screw structure lacks an effective support and guiding mechanism, making the power head assembly susceptible to external interference during movement. This can lead to offset or vibration, resulting in decreased workpiece surface quality and even machining failure. Long-term unstable movement can also cause additional stress on critical components such as the lead screw and nut, accelerating fatigue damage and increasing maintenance costs and downtime. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-station power head tool holder to solve the problems mentioned in the background art. Existing multi-station power head tool holders mostly use a single-rod lead screw and nut combination structure to achieve displacement adjustment of the power head assembly. When adjusting the displacement, the single-rod lead screw structure lacks an effective support and guiding mechanism. During the movement, the power head assembly is easily disturbed by external forces, resulting in deviation or vibration. This can easily lead to a decrease in the surface quality of the workpiece, or even cause processing failure. Long-term unstable movement can also cause additional stress on key components such as the lead screw and nut, accelerating their fatigue damage and increasing maintenance costs and downtime.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-station power head tool holder, comprising:

[0005] Support base;

[0006] The movable part is located inside the support base;

[0007] The first movable seat is located on top of the movable part;

[0008] The second lead screw is rotatably mounted inside the first movable seat via a bearing seat. The second movable slider is mounted on the second lead screw and is slidably connected to the first movable seat. The second movable seat is mounted on the top of the second movable slider.

[0009] The second guide rail is symmetrically fixed to the top of the first movable seat. The second guide slider is slidably arranged on the outer side of the second guide rail, and the top of the second guide slider is fixed to the second movable seat.

[0010] Side guide blocks are symmetrically fixed to the outside of the second movable slider, and the side guide blocks are slidably connected to the first movable seat.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 7 This utility model provides a technical solution: a multi-station power head tool holder, comprising: a support base 1; a movable part placed inside the support base 1; a first movable seat 8 disposed on the top of the movable part; a second lead screw 23 rotatably mounted inside the first movable seat 8 via a bearing seat, a second movable slider 5 mounted on the second lead screw 23, the second movable slider 5 being slidably connected to the first movable seat 8, and a second movable seat 9 bolted to the top of the second movable slider 5; and second guide rails 26 symmetrically fixed to the top of the first movable seat 8. A second guide slider 27 is slidably mounted on the outer side of the second guide rail 26, and the top of the second guide slider 27 is fixedly connected to the second movable seat 9; a side guide block 24 is symmetrically fixedly mounted on the outer side of the second movable slider 5, and the side guide block 24 is slidably connected to the first movable seat 8; a second guide rod 25 is symmetrically slidably mounted inside the side guide block 24, and the second guide rod 25 is fixedly connected to the first movable seat 8; a drive unit is located on one side of the first movable seat 8, and a second lead screw 23 is connected to the drive unit; a power head assembly 20 is mounted on the top of the second movable seat 9.

The T-shaped limit slider 10 slides on the outside of the first guide rod 11, which improves the adjustment stability of the first slider 3. The first slider 3 drives the first moving seat 8 and the second moving seat 9 to move and adjust as a whole. The first moving seat 8 drives the first guide slider 7 to slide stably on the first guide rail 6. The machine tool protective cover is an armor-type machine tool protective cover, which is designed to protect the machine tool. It is made of modular metal or plastic armor plates connected by hinges to form a retractable scale structure. It can extend and retract synchronously with the moving parts to achieve protection without dead angles. The edge sealing design can effectively block pollutants and reduce noise and vibration.

[0031] The specific architecture and operation logic of the servo motor achieving coordinated control through an external controller in this application are consistent with the existing technology in this field. The servo motors used are all equipped with encoders, which can provide real-time feedback on the speed, position and other information of the servo motor. This control method has been maturely applied in many similar industrial scenarios, so it will not be discussed in detail here.
